  • 8400MHz flux densities for Southern sources

    We present 8400-MHz flux densities for 1194 southern radio sources. The sources were selected from the Parkes 2700-MHz Survey to include all those stronger than 0.5Jy at that...
  • 7C survey of radio sources at 151 MHz

    The 7C survey of radio sources is being made with the Cambridge Low-Frequency Synthesis Telescope at 151MHz, with an angular resolution of 70x70cosec{delta}.arcsec^2^. We...
  • Metrewave Extragalactic Variability

    We report a detailed statistical study of the intensity variations in 412 extragalactic radio sources randomly selected from the ~2000 sources which have been observed with the...
  • Optical identifications of Molonglo sources

    Optical identifications have been sought for 304 radio sources from the declination -20{deg} region of the first Molonglo deep survey. Optical objects have been measured using...
  • Magnetic fields of radio pulsars

    The mechanism of magnetodipole braking of radio pulsars is used to calculate new values of the surface magnetic fields of neutron stars. The angles {beta} between the spin axes...
  • RCR sources in Plank maps

    Abstract-Fields of the Planck cosmic-microwave background maps in the regions of radio sources of the RCR (Ratan Cold Refined, Cat. J/other/AstBu/65.42) catalog have been...
  • AGN long-term variability

    Abstract-A complete sample of 104 bright active galactic nuclei (AGNs) from the "Planck" catalog (early results) were observed at 36.8GHz with the 22-m radio telescope of the...
  • Compact radio sources near Galactic center

    Using literature data on approximately 400 compact radio sources detected with the Very Large Array and located in the direction of the Galactic center within 2{deg} of the...
  • Flat-spectrum radio sources long-term variability

    The paper reports the results of ten-year centimeter-wavelength observations with the RATAN-600 radio telescope of a complete sample of 83 flat-spectrum sources from the GB6...
  • Geometry of radio pulsar magnetospheres

    Data on the profiles and polarization of the 10- and 20-cm emission of radio pulsars are used to calculate the angle {beta} between the rotational axis of the neutron star and...
  • Steep and ultra-steep spectra RC sources

    We present the results of spectroscopy of 71 objects with steep and ultra-steep spectra (alpha<-0.9, S{prop.to}nu^alpha^) from the "Big Trio" (RATAN-600-VLA-BTA) project,...
  • Radio source 111MHz interplan. scintillation. II

    A complete sample of radio sources has been studied using the interplanetary scintillation method. In total, 32 sources were observed, with scintillations detected in 12 of...
  • Sources from the WMAP catalog

    Observations of a complete sample of sources from the WMAP catalog were obtained at 22.2 and 36.8GHz on the RT-22 radio telescope of the Crimean Astrophysical Observatory. We...
  • Complete sample of flat-spectrum radio sources

    We present the results of twenty-year observations of a complete sample of 68 flat-spectrum radio sources with flux densities S3.9GHz>200mJy carried out at centimeter...
  • VRI observations of radio source S5 0716+71

    The results of VRI photometry of the gravitationally lensed system Q2237+0305 carried out on the 1.5-m telescope of Maidanak observatory in 2004-2005 are presented. The distance...
  • Radio sources near North Celestial Pole

    We have used the RATAN-600 radio telescope to study the spectral characteristics of a uniform sample of 504 radio sources from the NVSS catalog (Cat. VIII/65) near the North...
  • RATAN-600 Zenith-Field sky survey (RZF) catalog

    A catalog of radio sources detected in a deep RATAN-600 survey is presented. The catalog was obtained in the region 0h<=RA(2000.0)<=24h, Dec(2000.0)=41:30:42+/-2, at the...
  • Integrated Radio Luminosities of Pulsars

    The integrated radio luminosities of 311 long-period (P>0.1s) and 27 short-period (P<0.1s) pulsars have been calculated using a new compilation of radio spectra. The...
  • BV(RI)c photometry of S5 0716+714

    Photometric observations of the radio source S5 0716+71 were obtained in Johnson-Cousins BVRI filters from 1998 to 2001. with Zeiss-600 and Zeiss-1000 telescopes of SAO of the...
  • Flux-density-complete sample of radio sources

    We present the results of observations of flux-density- complete sample of radio with the RATAN-600 radio telescope at 0.97, 2.3, 3.9, 7.7, 11.1, and 21.7GHz. The sample was...
